RE: Do you send your DD/DS to preschool with a sippy?
Rachel, your preschool will undoubtedly give you a list of things to bring and not bring.
At Sarah's school, they started the year by asking all of the parents to provide a sippy cup for snack time (the school provides snack). But their goal was that by January all the kids would be drinking from a regular cup at snack. It took Sarah a little longer than that :) , but she didn't need that sippy for the whole year.
But I had to send lunch, including the beverage. I sent a straw sippy with milk. I know a lot of other kids had a juice box instead, but I preferred to send milk.
So the policies at your school will vary, but it will probably be something like this.
